Abstract: Rice is the major source of food for more than half of the world population. Rice suffers from many biotic and abiotic factors which results in the lower productivity. Blast disease is considered as major threat to rice cultivation. Thus, 7 fungicides, 4 bio agent and 7 plant extracts were evaluated. Among fungicides tested, all the fungicides found effective but Carbendazim and Propiconazole showed inhibition of 84.07 per cent and 74.25 per cent respectively at 500 ppm. Among the bio-agents tested, Trichoderma viride showed maximum inhibition with 64.44 per cent followed by Trichoderma harzianum with inhibition of 59.04 per cent, the least inhibition was recorded in Bacillus subtilis with inhibition of 47.48 per cent. The extracts of Lantana camara (55.80%), Neem (53.06%) and Nilgiri (51.83%) were showed maximum inhibition of pathogen at higher concentration.
